Allen-Bradley 1606-XLS240F 48V 240W Power Supply

Allen-Bradley 1606-XLS240F 48V DC Power Supply

Product Introduction

The 1606-XLS240F is a performance switched-mode power supply from the Allen-Bradley Bulletin 1606-XL series. This unit accepts AC 100–240 V or DC 110–150 V input and produces a regulated 48 V DC output. It delivers 240 W of rated power with 5 A nominal current. Engineers choose this model for sensor networks, solenoid banks, and control panels that run on 48 V DC rails.

The 1606-XLS240F carries UL 60950-1, cUL, and CE approvals. Its 92.0% typical efficiency keeps cabinet heat moderate. Moreover, a 50% power reserve supports short load peaks without shutdown. Spring clamp terminals speed up wiring, and a DC OK relay contact reports output status for diagnostics.

Technical Specifications

The 1606-XLS240F accepts AC 100–240 V nominal and DC 110–150 V input. Output voltage is DC 48 V nominal, adjustable from 48 V to 56 V. Output current reaches 5 A nominal, with a range of 5 A to 4.3 A across the adjustment band. Rated power is 240 W.

Efficiency reaches 92.0% typical, and typical power losses are 20.9 W. Ripple and noise stay at 100 mVpp maximum. Power factor is 0.92 typical, which meets modern mains quality expectations. Derating runs at 6 W/°C from +60 to +70 °C. Additionally, the 50% power reserve covers short overload peaks for motor loads and capacitor charging.

Mechanical and Environmental Parameters

The unit body measures 124 mm high × 60 mm wide × 117 mm deep. It weighs 0.90 kg, keeping DIN rail loading light. Protection rating is IP20, suitable for enclosure mounting. Operating temperature spans -25 to +70 °C. Storage temperature ranges from -40 to +85 °C non-operating. Relative humidity is not published in Bulletin 1606-TD002.

The slim 60 mm width saves rail space in dense cabinets. Furthermore, spring clamp terminals accept solid and stranded wires without screw tightening.

Installation Guide

First, snap the 1606-XLS240F onto a standard 35 mm DIN rail inside the control cabinet. Next, connect the AC input to the L and N terminals, or wire the DC input to the positive and negative terminals. Then connect the 48 V output to the load circuit, observing polarity marks.

After wiring, set the output voltage with the front potentiometer between 48 V and 56 V. Finally, wire the DC OK relay contact to a monitoring input if status feedback is needed. Mount the unit vertically and keep clearance above and below for convection cooling. Check the derating curve above +60 °C before full-load operation.

FAQ

Q1: What input voltage does the 1606-XLS240F accept?
A: The unit accepts AC 100–240 V nominal and DC 110–150 V. This dual input range covers most industrial supply systems.

Q2: What is the output rating of this power supply?
A: It provides 48 V DC at 5 A nominal, or 240 W rated power. Output adjusts from 48 V to 56 V.

Q3: What does the 50% power reserve provide?
A: The supply can deliver brief peaks up to 150% of rated power. This reserve supports motor starting and capacitor charging without shutdown.

Q4: Does the 1606-XLS240F include communication?
A: No. It has no communication port or protocol. It does provide a DC OK status indicator and relay contact for basic monitoring.

Q5: How does temperature affect output power?
A: Full power is available up to +60 °C. Above that, derating applies at 6 W/°C up to +70 °C. Plan cabinet cooling accordingly.
